Effectiveness of Kantutay (Lantana camara Linn.) Extract against Rice Stem Borer

Abstract

This experimental study determined the effectiveness of the Kantutay (Lantana camara Linn.) as an organic pesticide against rice stem borer (Sciropophaga incertulas). A single factor randomized complete block design was utilized for efficacy tests of the L. camara extract under laboratory and field conditions. Results showed that the extracted L. camara had an insecticidal activity against the rice stem borer. The pure concentration obtained the highest mortality rate – 86.11 and 85.19% under field and laboratory conditions, respectively. Under field conditions, the plant’s extract was significantly less effective compared to the commercial pesticide. However, it was not significantly different in terms of effectiveness under laboratory conditions.
